I wanted to make aperiodic pixel art for a long while. I am so happy to close this project after years of rumination. Now, any image can be asymmetrically converted to monotiles.

We often think of our mistakes, how to minimize them, and remove them. But out there is a life we could grow into. Why not explore it more?

The more energetic a photon, the smaller it gets. Would there be a point in which they would spontaneously convert into a black hole?

Rather than having anomalous risk preferences; it looks like people have complexity aversion to "hard" decisions, especially on valuation, which drives behavioral anomalies. Herbert Simon ftw.
